Summary
Pulsant
hosting transit business
Six IPv6 /32s, which is six registry memberships, which is six companies that used to exist.
What it's used for
- Hosting, colocation and transit in the UK. 179,456 addresses in 57 IPv4 prefixes, six IPv6 prefixes, and 147 observed BGP neighbours.
Notable
- Three acquired brands survive in the netnames:
UK-ONYX-960119,UK-ONYX-20031216,UK-EDNET-990924,UK-EDNET-20040831,UK-ASUK-20020429andUK-ASUK-20101221. - The oldest is January 1996; the newest of these is December 2010.
- All six IPv6 announcements are
/32s from unrelated aggregates:2a00:85a0::,2a01:5ae0::,2a01:6ca0::,2a02:16e0::,2a02:16f8::and2a02:2b38::. - Six sampled addresses answered, all under a fourth brand:
servers.dedipower.net. - Two RDAP records could not be retrieved.
Interesting
- A
/32is the standard IPv6 allocation to one registry member. Holding six of them, from aggregates issued years apart, is not how a single company grows; it is what happens when six memberships are bought and folded into one operation. The IPv6 table therefore counts the acquisitions more cleanly than any of the IPv4 records do. - The netnames date those purchases from the other direction.
UK-ONYX-960119was filed by a company that no longer exists, and it still describes the same addresses thirty years later, because renaming a registry object gains nothing and risks breaking every reference to it. - Four brands appear across the AS name, the netnames and the reverse DNS. Anyone trying to attribute this address space by name gets four different answers depending on which record they read, and all four are correct.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
